Belowthe mechaniszrr just above describedi is another: internally threaded pipe 30; which is pivotally and. removably mounted on alongitudinal brace rodDiFig. 13) and held in. place by a bolt, as shown at 3|. Into the pipe 30 is threaded the rod 32,1to one end-of; which is affixeda wheel 33 havinga handle Skier manipulating said wheel 33.; The rcd32- is held to one leg 35 of they chair F by a pivotedholding member 36' (Fig. 14). By-these adjusting-devices the chair F-may be moved forwardly and backwardly and swung transversely so as to accommodate patients of. difierent ages and sizes, aswell as lengthsof arm (see Fig. 1). A strap'Ff is provided for the purpose of holding the patients body stationary whilehis arm is being-exercised. It will be seen that by the removable connection at 3| the threadedpipe 3% can be removed andefastened to a like member on another. cross rod D .when the-chair ismoved to the-position shown in dotted lines; I will now-describe the exercising mechanism.

rod 4|.

59 is given a back and forth motionthroughthe- .2 A motor M, preferably electrically operated, is connected by a belt N with a reduction gearing 0, all of well known types. The mechanism just described is mounted on a shelf'S beneath'the top B of the table A, as clearly illustrated in Figs. 2 and 4. By means of the threaded rod R the reduction gear O may be raised or lowered to make the belts N and T fit accurately. As

these parts are standard, it is not believed that a detailed description is either necessary or material, as the illustrations in Figs. 2 and 4 show them in detail in so far as their function in operating my mechanism is concerned. The belts T aremounted on grooved wheels W on the reduction gear extending to the larger grooved wheels X which drive my exercising devices to quired at different times during each exercising treatment.

For exercising the fingers and thumbs of a patient the same mechanism for producing the oscillating movement of the parts is employed.

In Fig. 7 a pipe shaft69 is journaled at I0 in a frame I I bolted to the underside of the top B of the table A. The shaft" extends through I the pipe shaft 59 and has the wheel I3, with a handlev 14 located on its outer end. The intermeshing bevel gears I5 and 16, counterweight TI, member I8, long arm 19, slidable connection 80 with the member 18, are all operated by the belt T driving grooved wheel 8|, with the same be hereinafter described. The grooved wheel X shown in Fig.3 is fixed on a pipe shaft 31 jou'rnaled in bearings 38 carried by a frame 39 bolted at 40 to the underside. of the top B of the table A.' The lower end of the frame, 39 supportsa I rod 4| (Fig. 3). A hub 42 on1the grooved wheel.

X fixes said wheel to'the pipe shaft 3'1; Through the pipe shaft 31 and rotatable therewith extends the rod 43, 'on the outer end of. which is mounted the wheel 44 having a-handle 45. The inner: end of the pipe-shaft 3'! isfixed'at 46 in a structure 41 which is bolted to acounter- At, the inner end of the gear wheel 48 meshing withv the smaller bevel gear wheel 49, whichlatter is affixed to a threaded rod 50. The rod 50passes through alip 5| and the lower end.52 of. the structure 41. perforation through the lip 5| is threaded, so that as the rod 50 is rotated by turning the wheel 44 the member 53, to which the lip 5| isafiixed', ismoved up or down, according to which way the wheel 44 isrotated. Themember 53 is slidably mounted in the member 41 (Fig. 6). The

' strips 54 held by screws into the member 41 retain the member 53 in place.

red 43 is the bevel" The 9 character of means for varying the length of the stroke of the long arm I9 by manipulating V wheel "I3, as previously described in the mechanism illustrated in Fig. 3.

It. will be understood that shafts 43 and I2 rotate with the pipe shafts 31 and 69.. While the wheels 44 and 13 are turningwhen the motor M is operating; such turning movement is not rapid and the handles 45.and I4cari be grasped forturning said whe'els'and operating either of the bevel gears 48 and 49 or.

Springs 81' are provided vto give the necessary resiliency. tothe cords whenthe device 'is being grips 9|.

A boss 55 is formed'on one face of the member V 53 and has a central aperture therein to receive a plug 55 extending outwardly from a boss'51 on one face of another plate- 58, which is slidably secured in a recess 59' in a long arm 59 by means 1 of the strips 60'held by screws to oneface of the arm 59. The lower end of the arm 59 has a recess therein which receivesanend ofthe As the member 41 rotates; the long arm connection shown in Figs. 3 and 6; The length of the strokeof the upper end ofthe arm 59 is regulated by manipulating the screw 50 through the gears 48 and 48 when rotated by turning the wheel 44. The upper end of the arm 59 has a slot 5| therein which receives a projection 62 secured to a cylindrical member 63 by a bolt 64. Between the projection 62 andthe member 63 a recess 98 in the block 92.

operated. A cover 88 is preferably placed over the cords above the top B of the table A. Arms 89 bolted to the top B provide a support for the upper part of the'cord-carryingmechanism (Fig. 2). Above the top'B the cords are provided with the members 90 car'ryingthe'finger As the cords 85 are moved by the rocking of the arm 19 the finger 'grips'. 9| are moved up and down, and'the' length of such movement is regulated by the length of stroke of the up er end of the arm 19, which is controlled by moving the wheel I3 and shifting the screw-threaded rod connected with the bevel gears 15 and 16 (Fig. 7).

A support forthe hand of the patient is mounted on a block 92 superimposed upon another block 93 attached to the top of the tableA (Fig; 2),

and adjacent the finger-exercising mechanism;

On top of the block 92 is mounted the hand rest 94, which is provided with a projection 95 on the lower facewhich fits 'ina recess 96 in another block 91, which in turn is mounted in The lower side of the block 91 is preferably hollowed out as shown in Fig. 10, so as to provide a flange 99 to receive a screw-threaded rod I00, which is mounted in a wall IOI extending above the block 92.- The ,60 is a plate 65 slidably mounted in frame 56.

To the cylindrical member 53 is secured a glove 61 (Fig. 15), preferably formed-of canvas or other washable material, whereby said glove may be maintained in a sanitary condition. After the patients hand has been inserted in'the glove 6'! it may be secured about the wrist as by a snap button 68. When the arm 59 is oscillated and the hand of the patient issecured in the glove 61, movement is imparted to the arm of the patient corresponding to the length of' the stroke of the arm 59. Thus an exercising movement is imparted to the patients arm, which movement may be varied as to length of stroke depending on the nature of thefmovement retop of the block 94 is secured a strap I05 to-be buckled about the wrist and part of the palm of the-patients hand. By the rotatable feature of thehand-supporting block 94 said block can be adjusted to provide for the exercising treatment of .both'the fingers and the thumb of either hand. As'previously described/the lengthof the carries a cylinstroke for the exercising mechanism for the fingers and thumbs is regulated by the length of stroke of the upper end of the arm '19, which is regulated as previously described.

By'means of my mechanism positive means for the extension and deflection of the muscles of the arms and fingers of the patient is provided, and the arm or fingers being exercised are subjected to the treatment as the patient is held firmly in the chair F by the strap F, so that the patient is required to submit to such treatment as called for in his particular case. The block 94 is adjustable forwardly and rearwardly by the threaded rod I connected thereto.
